Fine 4–7 µm porosity: excellent retention of fine particles and precipitates.
Slow filtration (100 s): enhanced clarification for demanding analyses.
Wide diameter range (45–320 mm): fits standard laboratory funnels and filter supports.
AllFilter slow qualitative flat filter papers are designed for gravity filtrations where fine retention is more important than speed. With a 4–7 µm porosity and a filtration time of 100 s (DIN 53137), they efficiently retain fine particles and precipitates, providing excellent clarification of solutions. Their 80 g/m² basis weight, 0.16 mm thickness and burst strength above 20 kg/cm² ensure good mechanical stability. Available in diameters from 45 to 320 mm and supplied in boxes of 100 filters, they are well suited to chemistry and quality control laboratories.
